Separate operations require unchucking a turned cylinder from a lathe and clamping it into a vice on a milling machine. This manual transfer inevitably introduces angular datum misalignment, radial runout, and axial zero shifts typically ranging from 0.015mm to 0.050mm. A simultaneous multi-axis CNC Mill-Turn machine features a high-rigidity turning spindle with continuous C-axis positioning coupled with a full 5-axis B-axis milling head and sub-spindle. This allows turned surfaces, concentric pitch diameters, off-center milling slots, and cross-holes to be produced in one single coordinate setup, holding positional tolerances down to ±0.005mm.

Pure copper exhibits an exceptionally high reflectivity (over 95%) against standard industrial 1064nm infrared laser beams. Attempting to print pure copper with infrared lasers demands massive power inputs, leading to violent melt pool splattering, vapor blowouts, and severe porosity (often exceeding 5-10% internal void ratio). Our specialized green lasers operate at a 515nm wavelength, where pure copper's absorption efficiency jumps by more than 800%. This yields a continuous, stable melt pool producing structural components with greater than 99.8% physical density, optimal thermal conductivity (>380 W/m·K), and direct suitability for secondary CNC precision facing.

Standard commercial machining conforms to ISO 2768-m. However, for critical mating interfaces, bearing bores, and sealing surfaces, we routinely execute tolerances of ±0.005mm (±0.0002 in). In specialized hard-turning applications on ground steel shafts, we achieve true roundness and concentricity within 0.003mm. Achievable surface finishes range from Ra 0.8µm for standard fine milling down to Ra 0.2µm (8 microinch) utilizing specialized diamond tooling and fine-pass burnishing.

Thermal drift is the greatest obstacle to micron-level repeatability. TC Precision mitigates this through three distinct barriers: First, our high-precision machining centers are housed in temperature-stabilized cleanrooms maintained at 20°C ± 1°C. Second, our machines employ spindle oil chillers and ball-screw internal core cooling to dissipate motor and friction heat. Third, our CAM programmers integrate in-cycle Renishaw probe routines that measure reference artifacts periodically, dynamically feeding temperature-offset compensations into the CNC controller.

For rapid quote generation, we recommend sending native 3D CAD models in STEP (.stp), IGES (.igs), or Parasolid (.x_t) format for geometric volume extraction, accompanied by a 2D engineering drawing in PDF format specifying critical dimensions, GD&T callouts, surface roughness requirements, material specifications, and surface treatments (e.g., hard anodize Type III, nickel plating, passivation). For 3D printing projects, binary STL files are also accepted. Non-Disclosure Agreements (NDAs) can be executed prior to transfer.

Rapid prototyping batches (1-10 parts) typically ship within 3 to 7 business days following DFM sign-off. Low-volume production runs (100 to 2,000 units) require 10 to 18 business days, including secondary surface finishing and CMM reporting. Parts are coated with anti-corrosion protection, vacuum-sealed in ESD/moisture-barrier packaging with custom cutouts, and dispatched via priority international express (DHL/FedEx/UPS, 3-5 days delivery globally) or scheduled ocean/air freight for container-level orders.
